F_AF
High Temperature
The drive is too hot inside.
• Reduce the drive load.
• Improve cooling.
F_AL
Assertion Level
• The Assertion Level switch is
changed during operation.
• P120 is changed during operation.
• P100 or P121–P124 are set to
a value other than 0, and P120
does not match the Assertion
Level switch.
Before setting P199 or P121–P124,
make sure the Assertion Level
switch and P120 are both set for the
type of input devices.

Drive Hardware
F_CF
Control
An EPM has been installed that is
either blank or corrupted.
F_cF
Incompatible EPM
An EPM has been installed that
contains data from an incompatible
parameter version.
• Cycle power.
• Power down and install an EPM
with valid data.
• Reset the drive back to the
defaults (3,4 for P199) and then
reprogram.
F_cFt
Forced Translation
An EPM from an old drive put in the
new drive causes the drive to trip
this fault.
Press M (the mode button) twice to
reset.
F_dbF
Dynamic Braking
Dynamic braking resistors are
overheating.
• Increase active decel time (P105,
P126, P127).
• Check mains voltage and P107.
F_EF
External
• P121–P124 = 21 and that digital
input has been opened.
• P121–P124 = 22 and that digital
input has been closed.
• Correct the external fault
condition.
• Make sure digital input is set
properly for NC or NO circuit.
F_F1
EPM
EPM is missing or defective.
Power down and replace the EPM.
F_F2

F_F12
Internal
Contact technical support.
The drive is set up for Remote
Keypad control (P100=2 or 5), but
is not set up to communicate with
a remote keypad.
Set P400=1 or P600=1.
F_Fnr
Control
Configuration
The drive is set up for Network Only
control (P100=3), but is not set up
for network communications.
Set P400 or P600 to a valid network
communications protocol selection.
F_FoL
TB25 (4–20 mA
signal) Threshold
4–20 mA signal (at TB-25) drops
below the value set in P164.
• Check the signal and signal wire.
• Refer to parameters P163 and
P164.
F_GF
OEM Defaults
Data
The drive is powered up with
P199=1 and OEM settings in the
EPM are not valid.
Install an EPM containing valid OEM
defaults data or change P199 to 0.
Mains voltage is too high.
Check mains voltage and P107.
F_HF
High DC Bus
Voltage
Decel time is too short, or there is
too much regen from the motor.
Increase the active decel time
(P105, P126, P127) or install a
Dynamic Braking option.
